Our invention has referenoe to the milking of knit fabrics, and consists lifeerteiu combinations of devices hereinafter to 'be set forth.A

In the drawing, A supports the loop-carriei B, moving in the groove 0, constructed in A. Ierpendicular to A iserected the upright, D, fastened to A, w'hieh, supports gute E, moyingin grooved ways F-F F F.

Upon'theupright, D, is Secured the yarn-carrier H, pivoted at I I', ns also thecronk-shaft J, the turning of which gives motion .to 'gn-te E opereting 'in groove Q. The gato E has .pvotedto iight-x z', the swinging.

A-In regulnrtubulnr khitting, .the yum-carrier H vibrates in the spajce between the loopers a a', and since the rearjloope'r, 'Ivi'threspect totlieifo'rward movement of the loop-oarriers;--is the ivm-king one, it will be seen that theyarn-carricr,vibrating,as hereinafter deseribcd, will alwnyshavc the yarn in udvzmcc of said looper, on

WhioheYer-set of hooks itz-may be Working. i'

Thelooper-bearer' snigs','so as to. woijvkcncithcr Side of the lloop-carriers ee, and is moved and held in position-diy. the action pf eriik L turningiuslotp. Qn the opposite ends of era-nk L are the cross-bars S S", the ends of which a. re s imilarlyvbevelledifi r The reversing-rodeo 0"u1 e held in liollon tubes, surrounded by spiral springs u iiunged to hold them clown, except nhen forced upn'ur'd' by striking upouthe 'stop-blooks t t, when the upperend of the rod strikes ou the rack N, below which is the opening Vih'piece A.

I' side it may be working, it willbe seen'that lthey .yar

bevelled end of the cross-bar S, and turns itjirom its working plane, so that the upper end comes against the trip-plate T, when the gate E is raised by the turning of crankr J, which movements turn crank L one-half revolution, thereby changing the loopers a a to the opposite side ol 'the loopcarriers, and with them thc yarncarrier by the action of pin m moving in groove n.

The yarn-carrier H is made in two parte, the piece II being hinged to stationarysnpports at I I, and connected to the looper-bearcr by the pin'm nnoving'inA groove n, below which connection it is drawn toa spring, and the lower end formed into two notches, in one of which the piece H ofthe yarn-carrier is held with reference to lateral movements. Piece H is pivoted to H at'u, the lower end being tubed to hold the yarn yin proper position for knitting, and provided with suitable thiuiblcs along its length to hold the yarn in safe position with reference to the other mechanism. I 4 h A l l l At the ends of the -loopJcar'riers are placed the stop-blocks t t', which are fitted to fill the space betweenthe loop-hooks e e, and are Plaeedn'ear the limit desired to'bc knitted. When the movement'yof the lop'arril brings this block t under the reversing-rod, which has the reciprocating motion of gat-e E,said -rod-is raised, whereby the looper-bearer K ischanged to the lotlienside of the loopoarrier s,as before described.-

The feed-bar M is hinged'to the gate E at at', and gives'motion -to the loop-carriers by entering the toothed It will be seen that the feed-bar M is constructed so as cnly to reach `the distance of onetooth either way from itscentral position, which distance corresponds to that of the loop-hooks e e, and having passed through the said itoothed rack, is brought to the same central position, whichever side it'may have started on, and, of course, .must rmi the loop-carriers the space o one tooth. v Y

To cause feed-lever M to reach ina particular direction when it isdesired to move theloop-carriers in a certain way, and to reach inthe opposite direction when the motion of the carriers vshould be reversed, we`v secure the spring Y obliquely upon' crankshaft I1, the lower end'of the spring being held by a. staple to the feed-bar M. This oblique hanging of spring Y will give an oppositel inclination to feed-lever M at each half revolutionof the crank L, .thereby reversing the directien'of'the movements of the loop-carriers bythe action of the feed-lever, as just described. p

v It will be seen that the feed-lever M only moves the loop-carriers while passing the perpendicular distance of the V-shaped sides of opening V, and, having reached the centre of said opening, no further'motion will be lgiveir'tothe loop-carriers during the remainder of the movement of the feed-lcver until it shall be raised above the rack N and'reach out, so as to repeat the movementjust described. y

The loop-carriers B are constructed with a'iiange on one side opposite thetoothed rack N, which flange 'and rack lceepthe carriers from being raised by the actionof -loopers a a.l I

The plates B Bl are also placed somewhat further apart'at their lower yedges than theV upper edges, which construction facilitates the operation of lcopersaa, both in the certainty ofthelooper passing underI the loop -as' also 'in the ease of lifting it over the hook e. Y

The construction ofgroove Cfin picce A is made to correspond with the shape of loop-carriers),'asjust described, whereby theya-re kept from being raised or tipped sidewise by the action of ioopers a'a. l i

The tension-plate e is regulated to make the knitting loose or tight, as desired. A In operating this knitting-rnachine', the removable bobbin W, with the yarn wound onlit, is placediin-position, shown in iig. l, when the end of the yarn is passed' through the spring-,tensionldenice, through the eyelet and tubed end' of yarn-carrier H', and loops having been formedV in any convenient Imanner lon, thehoolis e e, with weight attached to them to lhold them down to the edge of plate B, thecrank J isturned, whereby the gateE is raised and lowered bythe action ofpcrank J operating in cam-grot v`efl When the gate E is fully lowered', =th e looper aj,beingpressedinto groo've' by the action of spring d', -isu'n position toi-nn .under the loop held on hook e, when-thc gate is raised, by which movement fthe loop is thro-wn over the yarn heldin yarn-carrier Il and off the hook e, and a new loop formed fonfth'e loop-hook, whilethe tipping ot' the looper, in its continued -npwa'rd movement.,f`rces it from the loop justknitted. 'i I 4When the gate E is fully raised, the feed-,lever M is thrown forward the distance of che 4tooth e by the spring-Y, and passing downward,guided*by the opening V, moves the carrier one space of hooks e e, which brings anotherhook in linewith the looper a, when the operation just described isrcpcatcd, and this i's conrod,v striking the stop-block, is forced against the bevellcd end of the cro'ss-barfS, which, thus turned from its working-plane;wil-l talie hold of the trip-plate T, and-by the'eontinued upward'movenient of the gate-E the crank-L will be t'urnedv,one,ha.lf revolution,- carrying vwith it the looper-bear'er K and yarn-carrier H, to the opposite` side ot-'loop-carriers B. This halfrevoluticn ofV crank L changes the inclination of'vthe spring Y Y hung obliquely upon the crank-shaft, whiclrj-changes-the direction of feed-bar M,`and, operating as before described, will rhove the loop-carrier-in'.tlieop`positc direction, whereby the looping-mechanism willoperate on the opposite side, and in'the opposite .direction-froinwhat itvdid before reversing, until it brings Stopblo-ck t underthe revcrsingfrod,: whcn the loopng-deviccfis againbroughtfto the place of vbegin-ning1` 4 It willtbus beseen'th'at we'kn'it s continuons' tub'u-larvfabrie on two straight'parallol rows of-Slcop-supporters. fHWhen it is desiried to narrow the fabric, the-two'endloopsarelifted from the end hooks and p.laced" upon the next inner oncsgjand'thc block t'mored inv one space, which may be repeated at bothv ends of. thccarrier, .which stop-block must blmovedontward, 'when additional loops will'bcformed on thehook's .e e.

The-'yarn-carrierH is liingedat I I', land is lguided in its -mcvements` by the connecting-pin m inovin'g in groove n. Since this groove n is always ata given angie with the plane. in' which gate-E moves, or. whichever tinued'until the 'stop-block tis brought, bythe'movcment ot"the'loopca`rricrs, under the reversing-rod 0, when will, of course, reverse the looping-device wherever the stop-,block -is placed.` 'I'flthe fabric is 'to be widened, vthe.

cari-*ier will receive a. vibrating motion' by thc'movementvof A gate E, tue upward movement.' of the groove throwing 1t outward andthe downward motion bringing it inward..

' Lhis vibrating movemcntof yarn-carrier is such that'lt isoutside f the lprcarriers wlx-ihtbcyare moved forward ,by the feeding-mechanism, bringing the yarn outside of the loop` irriers. When thc loopers descend, the yarn-carrier is moved in .toward the centre of tlxe carriers, thereby drnivi-ngthe yarn'tightly against the book e,

and serving also as a einher-when 'the loopA is cast over hook, e. A

The enlargement shown in groove n givesnn irregular movement'to'thc yarn-'carrier, allowing it to remainin its sinker position untilthe loop is' cast over bool( e. Y The operations hei-etof'ore'dcscribed are suoli vas relato to Astraight 'tubular work, varied only by widening or narrowing. i/"TUV 4u When it isdesired to knita dat web on one sidcfonly of tbejroivs'ef loops, the lever P'isrcleased from its catolnpin and-forced back of the same pin, vrhicli locks tbe looperfbear-ersfo'rivurd, and permits -ciarlk L to turn freely, but new only changing tbc feeding-device. I.
